Oleskiewicz was administered CPR at Wrigley and was then rushed to Illinois Masonic Hospital. She was kept alive until Tuesday so doctors could harvest her organs for donation “in a final act of kindness,” her mother said.

Here’s a statement from the school she taught at:

“There is no magic wand to fix what we cannot comprehend,” District 128 Supt. Kathleen Casey wrote in a letter to parents. “Maureen had a positive impact on countless students, parents and … colleagues. Her vibrant, positive outlook on life and her joyful nature will be missed more than words can convey.”

And here’s a statement from the Cubs:

“The Chicago Cubs are saddened to hear news of the untimely death of Maureen Oleskiewicz. We express our deepest sympathy to her family and friends. We will continue to keep her family in our thoughts and prayers during this difficult time.”

According to hospital officials, Oleskiewicz’s heart will go to a 14-year-old girl.

Our thoughts and prayers are with the family and friends of Maureen Oleskiewicz.
